Our friend Franz has been to the Tapout Tuning shop many times before and this time he was back to push his Brown Belt ATS-V even further. The last time he was here, we had the boost dialed back a bit to keep his Stage 1 LPFP within a completely safe operating range. He does not run methanol injection, so we have less fuel to work with in his application. To remedy that, we installed a DSX Auxiliary LPFP so we could safely push his turbos further than before.

While he was here, he also had us install the ATI Super Damper for even more quality and protection. After completing the tuning on the dyno, Franz’s car put down a very strong 756 whp. This car is a riot to drive especially as an M6 car!

Sam volunteered to be the very first CT4-V Blackwing Corsa exhaust customer and was excited to have us complete some additional modifications at the Tapout shop. We appreciate him allowing us to have his car for several weeks while Corsa got the first cat-back system installed on his car! After we got his car back to our shop, we installed our intercooler fill/bleed kit, a JB4, and colder spark plugs.

His baseline whp numbers on our DynoJet were 382 whp which is on the lower end of what these cars typically make from the factory, but we have seen other cars in this range as well. After installing our parts and massaging the JB4 settings on the Dyno, Sam’s car put down 446 for an impressive 64 whp gain!

Not only that, but the Corsa exhaust looks absolutely fantastic, and sounds even better!

We had another CT4-V Blackwing Atlanta Track Edition Car in the shop and this one got the upgraded turbo treatment. The previous Atlanta Track Edition car was serial number 017, and if you can believe it, this one was number 016!

The build on this car was more unique than most Brown Belt cars we build as this customer requested a special 100-octane tune and is running no ethanol. Because of that, this car is able to run its stock fuel system with no modifications. After completing the parts installation and dyno tuning, this CT4-V Blackwing put down 667 whp! And that was at the end of the summer when it was 105 degrees in the shop!

Adrian shipped his brand new 2024 CT5-V Blackwing shipped from Canada all the way to our shop in Central Ohio for our complete cam package build. This includes all kinds of goodies from GPI, Brian Tooley Racing and many more! We also installed a ported supercharger and throttle body from Kong Performance along with smaller upper pulley. To top it off we installed a set of Kooks headers and this thing sounds absolutely wicked!

After completing a custom dyno tune, this CT5-V Blackwing put down 749 whp on 93-octane fuel in 104 degree heat!

Rick drove his M6 CT4-V Blackwing Atlanta Track Edition all the way to the Tapout Tuning shop from Maryland for our complete Purple Belt Performance Package. As the name suggests, Rick enjoys his time on the track and wanted the power to back up the handling capabilities his Blackwing has in spades.

After completing all of the necessary modifications and getting his car strapped down tot he dyno, this Blackwing produced 613 whp!
